vGPU driver for rhcos4.19 / rhel9.6 directory issue

[CLNRMN]

Hi

We're running an OpenShift Cluster with 4.19.x, which uses rhel9.6. According to the documentation, you should not use the rhcos-4.19 version tag anymore; instead, you should switch to rhel9.6.

We tried to build the vGPU image with the following parameters and got the error that the folder was not found.

export PRIVATE_REGISTRY=registry.company.com/company
export OS_TAG=rhel9.6
export VGPU_DRIVER_VERSION=570.124.06

VGPU_GUEST_DRIVER_VERSION=${VGPU_DRIVER_VERSION} IMAGE_NAME=${PRIVATE_REGISTRY}/driver make build-vgpuguest-${OS_TAG}

ERROR: failed to build: unable to prepare context: path "/home/username/git/public/gpu-driver-container/rhel9.6" not found

To fix it, we've added the following line to the makefile to make it work.

diff --git a/Makefile b/Makefile

Probably related to this change here: #486

Just went here to report the same thing.
This whole thing is one huge mess.
